PBX and Key/Hybrid Systems
PBX and Key systems are the wave of communication for business everywhere. The key difference between PBX and Key/Hybrid systems are the amount of stations each can handle. Key systems are designed for clients with very small line size requirements and very basic needs. It usually handles between 16 to 48 stations. PBX systems on the other hand handle a lot more stations as well as more features and sophistication. PBX are designed for larger corporations and cost much more than a simple key system communication need. Another key advantage of PBX system is it allows for room for corporation growth over the years than that of a Key System or Hybrid system.

With the PBX of the Fujitsu you spend so much more money but you get a lot of different features as well as the ablility to grow and become a bigger corporation with larger features. The Key system just leaves you with the bare requirements for your small business
